To all whom t may concern.' Y Be it known that I, ALLAN J. STRIGKLAND, a citizen of the Unit-ed States, residing at Valdosta, in the county of Lowndes and State'oi:` Georgia, have invented certain new and useful Improvements in Insect Destroyers, of which the following isl a speciication.

This invention relates to poison Ydust distributors, and has for oneI of its objects to increase the eliciency and improvethe construction of devices oir' this character, and includes a container with means whereby the poison in dust or finely divided condi tion is disseminated by merely agitating the container, vertically.

Another object of the invention is to provide a device of this character having'means for controlling the discharge from the container.

Another object of the invention is to provide a device of this character including a resilient holder or handle for the container'whereby the eliciency' of the agitation is increased, andthe amount ot' fatigue to the operator is reduced.v l

With these and other` object-s in view, the invention consists in certain novel Jfeatures of construction as hereinafter shown and described and then speciically pointed out in the claims, and in the drawings 'illustrative of the preferred embodiment of the invention.

Figure 1 is a perspective view of the improved implement. f

Fig. 2 is an enlarged sectional elevation.

Fig. 3 is an enlarged sectional detail illustrating the construction of the coupling between the container and the protecting and guiding devices.

Figs. 4 and 5 are detached plan views of the discharge reducing members.

The improved device includes a container for the poison element, in powdered or otherwise finely divided condition, and represented as a whole at 10 and with' a screen 11 forming its bottom. The top ofthe container is formed with an air inlet opening, forv instance, radially arranged as represented at 12, and'withfa rotating closure 13. By this means, the sizes of the 'openings may be controlled to correspondingly control the amount of airV admitted to the container.

Attached at 14 to the container is a handle 15 terminating at the upper end in a hand grip 16 and turned into one or more coils 17 intermediate the ends. The distributing is accomplished by rapidly moving the container vertically through the action of the handle, and kthe resilient coils 17 materially increases the eiiciency of the agitation and also renders the action less fatiguing to the operator.

Loosely disposed withiny the container is an agitator plate 18 having a relatively small aperture 19, preferably at the center, and with aplurality of vertical guards or stops 20 inturned at their upper ends as at 21. Thevplate 18 is smaller than the nterior of the container, and thus operates loosely within the powderedV poison element,

and agitates the same .as the container is rapidly moved up and down by its handle I 16, the bars 2 04-21 Vpreventing the overturning of theplatev during the operation. When the container is actuated by rapidlv movingit upwardly and downwardly, the j finely divided poison element is caused to pass in a relatively thin stream through the aperture 19 and also between plate 18 and container-'and upon the screen 11 and thereby evenlyV distributed.

Surrounding the'container 10 at its lower end and Vdepending `below the same, is a flexible hood or guard 22 of rubber cloth or the like and held in place upon Vthe c on- .tainer by a band 23 of rubber or the like.

The hood or guard effectually prevents the poison dust from being blown about by the wind, and insures its conlinement to the plants being treated. y

The band 23 enables the hood member to be easily attached or detached, .or turned l up around the container when not. required.

Extending across the containerbeneath V'the screened portion, isa guard element 24,

preferably of relativelycoarse wire screen material, and with upturned portions 25 eX? tending between the band 23' and the body of the container, and thus held in place on the'containerftogether with the hood ,225'

ioo

The member 24 thus serves toprotect the screen 11 from contact with the branches or leaves of the plants being treated. K

lhen employed vfor dusting relatively large plants, the device thus far described is complete, but when used Vfor dusting, smaller i plants, a 'concentrating device: will be attached inaddition Ato vthe-hood 22 and 'guard 24 and consisting of a conical-shaped member represented as a Awhole at 26V and including converging sides and a reduced disprevented 'from downwarddisplacement.
